Rubber Transfer Molding
The rubber transfer molding process is ideal for the production of solid rubber parts, rubber parts with inserts, and parts that require bonding rubber to metal. Rubber transfer molding combines the advantages of injection rubber molding with the ease of compression molding. This process is most often used for forming rubber products that require:
Bonding rubber to fragile metal parts – such as wire
Mold designs that contain multiple cavities and can trap air
Intricate parts with lower volume requirements
Qualiform’s Rubber Transfer Molding Process
Our process of transfer molding involves pushing unvulcanized rubber through sprues into a heated mold. Similar to compression molding, transfer molding requires raw material preparation into pellets and/or pre-forms.
Rather than placing the preform in the mold cavity, the rubber pre-form is placed in a chamber “pot” at the top of the mold then placed in a press. In the pot, the material is compressed by a heated plunger and transferred through sprues into the cavity below. During this, the plunger is kept in place until the preform takes on the shape of the mold and the rubber is vulcanized. Once the part cures, hardens, cools, it is then ejected. Any excess cured rubber left in the pot is removed and the mold cavities are cleaned for the next molding cycle to begin.
Transfer Molding for Rubber to Metal Bonding
Transfer molding is an important part of the rubber to metal bonding process or over molding, the components are loaded into a heated mold either by hand or using a loading fixture. Material is then loaded into the well pot of the transfer mold. Once the mold closes, the rubber is heated and then transferred through the runner. The gate sprues into the mold cavities and around the metal insert. With the pressure and elevated temperatures, the rubber cures and vulcanizes, allowing the parts to be removed.
The rubber transfer mold consists of a piston, well pot, sprue plate, cavity plate, and a base plate with a knock-out system used to eject the parts after molding.
